Zovala zathu zambiri zimakhala ndi mikanda yokongola pamanja

Chiyambi cha polojekiti

• Kampani yathu imapereka zingwe zachitsulo zokhazikika kuti zikhazikitse milatho ya konkriti ndi zingwe zokhazikika za nsanja zazifupi zokhala ndi chingwe pantchitoyi.
  1. The superstructure ya mlatho waukulu ali mu mawonekedwe a prestressed konkire variable mtanda gawo bokosi girder, m'lifupi mlatho waukulu ndi 33.5 mamita. Njira mlatho lakonzedwa mu slats, ndi m'lifupi limodzi la mamita 12.5, njira mlatho utenga 30-mita muyezo span yaing'ono bokosi girder dongosolo. Pali ma girders ang'onoang'ono a 96 mumlatho wa Lile River wamamita 30, ndipo kulemera kwa bokosi limodzi ndi matani pafupifupi 100.

• 2. Chingwe chokhala ndi chingwe chimapangidwa ndi chingwe chachitsulo cha 15-91 epoxy sprayed ndi chitetezo cha HDPE chawiri-wosanjikiza, chingwe chimodzi cha diameterφ15.2mm, fpk = 1860MPa mphamvu. (mtengo wokhazikika)
  3. Makina azitsulo zonse zachitsulo zomwe zimagwiritsidwa ntchito mu polojekitiyi zimagwirizana ndi "Steel Strands for Prestressed Concrete" (GB/T5224-2014) ndi EN10138-3:2009, katundu wawo wa anti-corrosion amakwaniritsa zofunikira za ASTM. A882/A882M-02a ndi ISO 14655:1999. Kukana kutopa kwa chingwe chokhazikika pa chingwe kuyenera kukwaniritsa malire apamwamba a kupsinjika σmax = 0.45fptk, matalikidwe opsinjika a 200MPa, komanso kusweka kwa waya kwa ≤2% pambuyo pa mizungu 2 miliyoni.

Zopindulitsa

• 1.Zingwe za konkire (PC) zimagwiritsidwa ntchito kawirikawiri pomanga matabwa a konkire kuti apereke mphamvu zowonongeka ndi kulimbikitsa.
  2.Zingwezi nthawi zambiri zimakhala zowonongeka kapena zowonongeka mkati mwa konkire kuti ziwonjezere mphamvu zonyamula katundu ndi kuchepetsa kusweka.
  3.Kugwiritsa ntchito zingwe za PC kumathandizira kukonza magwiridwe antchito komanso kukhazikika kwa matabwa a konkriti. Zingwe za konkriti zokhazikika (PC) zimagwiritsidwa ntchito popanga matabwa a konkriti kuti apereke mphamvu zolimba komanso kulimbikitsa.
